DRS CENSE User Guide
DRS CENSE is a simple GPS device that displays your
current position to better than 5 metres accuracy. This
can be transcribed quickly and easily onto any form for later data capture.
Getting started
Unpack the device carefully, and if required attach the supplied lanyard by
slipping the loop through the slot in the top right corner, and then passing it
through to secure it.
Fit three AAA batteries by opening the flap at the back.
If rechargeable
batteries are used these
must
be 1.5v.
Ensure that the positive (+) terminals
are correctly aligned with the markings. The device will start up
– if it not to be
used immediately, switch it off to save power.
A set of high quality alkaline
batteries will last for approximately 15 hours of continuous use; since
the
device is not designed to operate indoors
, remember to switch it off when it
is not needed to save power! DRS CENSE will turn off automatically after 5
minutes if the GPS signal is lost, but may for instance continue to operate if
left on a car dashboard.
To switch on, press the power button. To switch off hold the power button
until the display goes blank.
